$SPX seems to have a potential ABCD pattern. Although the price continues to rise strongly after reaching the PRZ, the long upper shadow of the bearish candle at point D is still acceptable. Plus, the price has already broken new highs, so we can observe the reaction after the price reaches the PRZ.
If you want to short, just set the stop loss if the price breaks new highs subsequently. The stop loss level in the chart should not be considered, as the risk-reward ratio is extremely low.
The take profit level is the two yellow lines below, which are the standard take profit levels for the ABCD pattern.
